What would be the result if a 24 volt, 20 ohm contactor coil was wired in series with a
24 volt, 200 ohm control relay?
Give this one a try later!
Only the control relay would operate
A thermocouple can

Less than the smallest resistance.
With a motor running at full load, voltmeter leads are placed on L1 and T1 with no
measurable voltage detected. This indicates:
